Value Collection TCI40750550 Tension Control Bolt A490

Product Description

The VALUE COLLECTION TCI40750550 is a structural tension control bolt designed for high-strength steel-to-steel connections in construction and industrial applications. This fastener features a 3/4-10 UNC thread and measures 5.5 inches in length under the head, with a 1.375-inch head diameter. Manufactured to ASTM A490 and ASTM F2280 standards, it delivers the clamping force and material integrity required for structural bolted connections. Each set includes the bolt, nut, and washer, providing a complete fastener assembly. Licensed structural trades and steel erectors rely on this bolt type for code-compliant high-strength connections.

This tension control bolt is suited for structural steel framing in commercial and industrial construction where pretensioned bolted joints are specified by the engineer of record. The A490 material grade meets the requirements for use in heavy structural steel connections. The bright, uncoated finish is standard for structural applications where surface treatment is not specified or where field inspection of spline shear-off is required to confirm proper installation torque.

Key Features

• ASTM A490 and ASTM F2280 certified for high-strength structural use
• 3/4-10 UNC thread for compatibility with standard structural hardware
• 5.5-inch length under head accommodates multi-ply steel connections
• 1.375-inch head diameter provides broad bearing surface
• Bright, uncoated finish allows visual and spline-break inspection
• Includes matching nut and washer for a complete installation assembly

Compatibility

Designed as an OEM-style replacement or direct-use structural fastener for 3/4-10 UNC tension control bolt applications conforming to ASTM A490 and ASTM F2280 specifications in structural steel connections.

Installation Notes

Tension control bolts are installed by licensed ironworkers or structural steel erectors using a shear-wrench tool that engages the splined end of the bolt and shears it off when the specified pretension is reached. Bolt holes and mating surfaces should be clean and free of debris before assembly. Follow AISC and RCSC specification requirements for structural joint installation, including proper nut and washer orientation. Do not reuse tension control bolts once the spline has been sheared.
